Periodic Time Event Process
About the Periodic Time Event Process
With the Periodic Time Event process, you can schedule arbitrary and repetitive
times at which the process will produce a trigger, or a series of triggers. You can
use these time based triggers to invoke an event, such as triggering another
process, actuating an external device, and so forth.
When you define a Periodic Time Event process, you can specify periodic trigger
times, the trigger mode, and whether or not the process writes a message to the
message log when it invokes a trigger event.
Note To produce a trigger the Periodic Time Event process must be active at
the time you wish the trigger event to occur, so it is important to keep that
in mind when designing your test.
Note The Periodic Time Process will not trigger immediately after the test
starts, regardless of the process settings. The minimum amount of time
required for the process to trigger after the test starts is approximately
one minute.
Periodic Time Event
example
Suppose you need to start warming up a temperature chamber before a technician
arrives at your facility, so that it has achieved and stabilized at the desired
temperature by the time the technician begins testing. Further, suppose the
technician is scheduled to perform tests at 8:00AM on Mondays, Wednesdays,
and Thursdays beginning in March and continuing through May.
In this case you could use a Periodic Time Event process to trigger a Temperature
Control process hours before the technician arrives on the days and in the months
testing is scheduled.
